Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a seat heater for heating the seat of a vehicle, aircraft, ship, etc.

Conventional configurations and their problems Generally speaking, seats in vehicles are being provided with seats to allow for heating. That is, as shown in FIG. 1, the seat heater 5 is installed between the main pad 2 and the cover pad 3 of the seat 1, or between the seat skin 4 and the cover pad 3 (not shown).
is inserted.

By the way, in the conventional seat heater, as shown in FIGS. 2 and 3, a heating wire 7 is wired on a non-fabric 6, an upper fabric 8 is placed on top of the heating wire 7, and the lower fabric 6 and the upper fabric 8 are bonded together. It is constructed by heat welding with a synthetic resin.

In the seat heater having such a configuration, as mentioned above, the lower fabric 6 and the upper fabric 8 are completely bonded, so
The movement of the upper and lower fabrics 6 and 8 is restricted, and the flexibility of the fabrics is lost. Therefore, when it is attached to a seat, it has the disadvantage of impairing the cushioning properties of the seat itself.

Also, when installing the seat heater on the seat,
Some methods of fixing the seat heater's position within the seat include sewing the seat heater fabric onto the seat skin, but in such cases, the elongation rates of the seat skin and the seat heater fabric become extremely different. However, the seat heater restricts the stretch of the seat skin when sitting on the seat, which has the disadvantage of making the seat skin feel taut.

Purpose of the Invention The present invention takes into account the above-mentioned conventional problems and aims to provide a highly flexible seat heater that does not impair the cushioning properties of the seat.

Structure of the Invention In order to achieve the above object, the present invention includes a heating wire and two pieces of fabric that sandwich the heating line and are overlapped and bonded to each other, and among the two pieces of fabric, One piece of fabric has at least flexibility, and one or both of the two pieces of fabric is provided with a notch having a certain width extending inward from the edge of the seat heater. Yes, the seat heater exhibits flexibility in the notch, and when incorporated into the seat, does not impair the cushioning properties of the seat, and also follows the movement of the seat skin, making it possible to take in heat without feeling like a foreign body. It is.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 and 5.

In the figure, 9 is a lower cloth, 10 is a heating wire wired in a meandering manner on the lower cloth 9, and 11 is an upper cloth which is laid on top of the heating wire 10. The lower cloth 9 has a plurality of notches 12 that are deeper inward than both side edges and have a certain width so as not to obstruct the wiring of the heating wires 10. In addition, upper fabric 11
is made of flexible fabric. The lower fabric 9 and the upper fabric 11 are bonded together using an adhesive resin.

In the seat heater with the above configuration, the lower fabric 9 has the notch 1
2, the only part corresponding to this notch 12 is the flexible upper fabric 11, and this notch 1
In No. 2, the seat heater becomes highly flexible. Therefore, when it is attached to a seat, it does not impair cushioning properties, and since it follows the movement of the seat skin, it does not feel like a foreign body and allows for comfortable heating.

FIG. 6 shows another embodiment of the present invention, in which the upper fabric 11 is also provided with a notch 12. The completed seat heater is shaped like a plurality of strips. This seat heater is also highly flexible as described above and follows the movement of the seat skin. Particularly, this configuration is effective when inserted into a pouch formed on the lower surface of the seat skin.

Effects of the Invention As explained above, the present invention increases the flexibility of the seat heater by providing a notch in the fabric of the seat heater, does not impair the cushioning properties of the seat, and allows heating without causing the sensation of a foreign body. This makes it possible, and its practical effects are great.
